The choice of materials for the lining of walls and ceilings can significantly affect the spread of a fire, and its rate of growth, even though they are not likely to be the materials first ignited. This is particularly important in circulation spaces where linings would offer the main vehicle for fire spread, and where rapid spread would be most likely to prevent occupants from escaping.
Several properties of lining materials influence fire spread. These include the ease of ignition and the rate at which the lining material gives off heat when burning. The guidance relating to the European fire tests and classification provides for control of internal fire spread through control of these properties.
A protected corridor is necessary in a building to protect occupants escaping in the event of a fire. The fire performance of the boards and wall coverings that comprise the outer faces of partitions are subject to the guidance given in the Building Regulations.
PAROC stone wool based acoustic boards are fire safe and suitable to be used in all kind of corridors.
